Here is an idea of how some basic stuff crosses arts and cultures. This guy taught in Japan for 11 years. Among his students were 2 of Sagawa's long time students. He is a very interesting and wonderful man with some intriguing ideas of his own about Daito Ryu and Internal Chinese arts.
What were his ideas about Daito ryu and the Chinese arts? I'm sure that from teaching in Japan for that long and getting hands on with two of Sagawa's students, there were some interesting comments and observations. Similarities? Differences?
